ABSTRACT:
A collector-up binary structure of the type having spaced semiconductor regions forming a plurality of active devices for interconnection as a binary circuit is disclosed. The structure includes a semiconductor body of one conductivity having a planar surface, and spaced first, second, third and fourth transistors formed in said body. Fifth, sixth, seventh and eighth transistors are included, said fifth and sixth transistors being formed in the base regions of said second transistor and said seventh and eighth transistors being formed in the base region of said fourth transistor. Lead means provides ohmic contact to each of the respective regions of the respective transistors and interconnecting means is provided for connecting the plurality of active devices as a binary circuit. A structure further including ninth and tenth source transistors is also disclosed.
